Study of sound is called _____________?
Correct answer: B. Acoustics
- A. Soundlogy
- B. Acoustics
- C. Neurology
- D. Physiology
Explanation
Acoustics is the branch of physics that studies sound, including its production, transmission and properties. Neurology studies the nervous system, while physiology studies the functions of living organisms. The likely mistake is choosing physiology because hearing involves a biological process, but the physics of sound belongs to acoustics.

About Speed of Sound
The speed of sound depends on the properties of the medium, including its elasticity and density, and in gases it varies mainly with temperature. Questions connect speed with frequency and wavelength, compare sound in solids, liquids and gases, and distinguish the speed of propagation from the oscillating particles' motion.
